Hey brothers. I have a question. Me, 28 y/o have my first sex last night. The foreplay is great and amazing. I'm a bit nervous about coming too soon. And also since it's my first time.

After a bit of foreplay, my penis is rock hard and I can enter her and thrust like an animal. But as soon as I stop to take a break or catch a breath, my penis went soft. So, WTF?

And then we kiss and foreplay again and she gave me a oral that makes me hard again and I enter her again annnddd my penis is soft again after thrusting.

Is this normal for the first time sex? Thank you boys!
